That’s a different scenario. That was over Syrian/Turkish airspace and Russia likely knew they don’t have a leg to stand on there considering the close vicinity of the border and conflicting reports over the bomber’s flight path. Not to mention that Turkey is a lot closer to Russia than the average NATO state.
I don’t think it could escalate to a full war, but shooting down aircraft in intl. airspace is much more serious than a bomber that has strayed into your national airspace.
